SIGNORS OF ONE-HALF TO SAID PINFZDA, ONE-FOURTH TO SAID ANABISA, AND ONE-FOURTH TO FELOMINO V. LANGLANG, ALL OF SAN FRANCISCO, CALIFORNIA ooMrAss Application filed January 12, 1932. I Serial No. 536,180.

Our invention relates to improvements in compasses, and it consists of the combinations, constructions and arrangements hereinafter described and claimed.

An object of our invention is to provide acompass, which is especially designed to be attached to a fountain pen or pencil and which, in closed position, will occupy little space so that a cap can enclose the compass. The outer diameter of the cap is preferably the same as the outer diameter of the pen or pencil, so that the device will resemble a standard pen or pencil when the cap encloses the compass. It is obvious that the compass can be secured to a holder if it is not desired to have it connected to a pen or pencil.

A further object of our invention is to provide a device of the type described, which is extremely simple in construction and which is durable and eflicient for the purpose intended.

Other objects and advantages will appear in the following specification, and the novel features of the device will be particularly pointed out in the appended claims.

Our invention is illustrated in the accompanying drawing forming a part of this application, in which Figure 1 is a side elevation of the device shown operatively applied to a pen, the cap for the compass being shown in section;

Figure 2 is a similar view, with a compass cap and pen cap removed;

Figure 3 is a section along line 3-3 of Figure 2; and

Figure 4 is a section along line 44 of Figure 2.

In carrying out our invention, we make use of the barrel 1 of a standard fountain pen or pencil, or the barrel 1 may be merely a holder. Figure 3 shows the end of the barrel 1 as being threaded at 2 for removably receiving a cap 3, shown in Figure 1. An insert 4 is placed in the open end 5 of the barrel 1 and rests upon a shoulder 6. The insert is preferably cemented in place, although it may be threaded into position if desired.

The insert 4 has a square opening 7 for receiving the square end 8 of a screw 9. The upper end of the screw is bifurcated at 10 and receives a pin 11, which, in turn, pivotally carries a compass indicated generally at 12. The compass has a pointed member 13 which has cam portions 14 pivotally secured to the pin 11 and contacting with a knurled nut 15. The compass '12 also has a pencil or pen member 16 which is provided with cam ends 17 that are also pivoted to the pin 11 and bear on the nut 15. A spring 18 passes around the pin 11, (See Figure 3), and bears against the members 13 and 16 so as to urge the members from theposition shown in Figure 1 into that shown in Figure 2. i From the foregoing description of the various parts of the device, the operation thereof may be readily understood.

WVhen it is desired to use the compass, the cap 3 is removed and then the nut is actuated so as to permit the spring 18 to move the members 13 and 16 into the desired position. The nut 15, when turned in one direction, permits the spring 18 to move the members 13 and 16 into open position and when turned in the opposite direction, engages with the cams 141 1 and 17-17 for swinging the compass members toward each other. It should be noted that the outer diameter of the cap 3 is the same as the outer diameter of the barrel 1.

The fountain pen or pencil may be used in the ordinary manner after first removing the cap 20. A clip 21 is carried by the cap for the purpose of supporting the device when closed in the pocket. If a pencil is used, the cap 20 would be dispensed with and the clip 21 would be secured to the cap 3. If the barrel 1 constitutes merely a holder without the provision of a pen or pencil, the cap 20 would be dispensed with and the barrel could then be used for housing leads and erasers, if desired.

While we have shown only the preferred form of our invention, it should be understood that various changes or modifications may be made within the scope of the appended claims without departing from the spirit of the invention.

We claim:

1. In combination, a holder, an insert carried by the holder and having a square opening, a screw having a square head received in member the opening and a bifurcated end, compass members having cam-shaped portions, a pin for pivotally securing the portions to the bifurcated end, a knurled nut mounted on the screw, and a springldisposed in the bifurcated member and havinglits ends bearing against the compass members for causing the cam portions to contact with the nut.

In combinatiomaholder, an insert car- .ried by the holder and having a square opening,.a-screw having a square head received in the opening and a bifurcated end, compass members having cam-shaped portions, a pin for pivotally securing the portions to the bifurcated end, a knurled nut mounted on the screw, aspring disposedin the bifurcated and having .its ends bearing against the compass members for causing the .cam, portions to contact with the nut,.and a capfor receiving the compass members when the latter are mclosed positlon, said cap being removably securedto theholder.

3. In combination, a cylindrical holder constituting a handle, athreaded shankof less diameter than the holder and being carried. thereby, .anut of lessdiameter than the iolder-and being mounted on the shank, compass members pivoted to vthe shank and hav- .ing cam portions bearing againstithe nut,

spring meansfor holding the cam portions of the compass membersagalnst the ,nut, and a cap of the same outer diameter as the outer diameter. of the holder and being. removably carried thereby,.said caphousing the compass members, nutand shankwhen the compass members are inaclosed position.
